To all whom it may comm:

Be it known that I, DONALD R. MORRISON a subject of the King of Great Britain, residing at Los Angeles, in the county of Los Angeles andState of California, have invente -new and useful Improvements in Tank Gaps, of which the following is a' specification.

This invention relates to cap closures for' gasoline tanks, engine radiators, and the e. V i

and having a movable member forming a cap piece. Another object is to provide means for retaming the cap pleoe in closed position and i for holding it against vibration and rattling.

Broadly, an object is to eliminate the bodily removal of the cap when filling its respective container and to provide for'the guick opening of the cap to enable the quick 11in of the receptacle.

Ot er objects will be made manifest in the following specification of an embodiment of the invention illustrated inthe accompanying drawings, in which:

Fig. 1 is a perspective of the improved device in its applied and closed position.

Fig. 2 is a plan viewv of the device with the cap member in open position.

Fig. 3 is a vertical central section of the device with the cap in closed position.

Fig. 4 is a side elevation of the device.

I In itspreferred embodiment, the invention consists of a'collar member 2 of suitable design and proportion and which is internally threaded at 3 so as to be mounted on the mpple 4 of any suitable receptacle as a radiator R of an automobile- The collar 4 is internally grooved at 5 to receive a cement- 6 which, when set, serves to permanently secure the'collar 2 in place and, therefore, prevent its surreptitious removal. The collar 2 is provided with a peripheral enlargement or flange 7 and the top face of thls is channeled or grooved to receive a suitable acking medium 8. At one side of the col ar there is provided a substantiall semi-circular overhanging lip 9.

T e collar is also provided-at one side with an extension lug or car 10 and through.

, formed, to be held by an appropriate tool and under the head is a spring Washer 14: bearing down on the contiguous end of a spring finger 15.

Pivotally mounted on the pivot bolt 11 and swinging between the sprmg finger 15 I and the top plane face of the neck 2 is a ca member. This cap member is substantia ly in the form of a disc 16 having at one passes. Thus the cap 16 is adapted to be swung into closing osition over the top of thecollar 2 and w en closed, one edge of the cap 16 passesv in under the overhanging lip 9 of the collar; The diametrically opposite edge of the cap 16 is provided with a semi-circular flange 18 to sweep into contiguity with the adjacent flange portion 7 of the collar 2.

When the cap isclosed, its lower surface forms a substantially leak proof seal when resting'upon the packing or gasket 8 em.-

bedded in the flange 7 of the collar 2 and thus prevents spilling of the liquid and providing, if desired, for the creation of a pressure vacuum in the receptacle to which the device may be attached. If, as is sometimes desirable, an atmos heric pressure is to be had in the rec'eptac e, then leakage or vent may be provided for as by. drilling a vent hole indicated at 19, in this instance in the cap 16.

The spring finger 15 is of such normal form that when it is applied it will be pressed down on the bearing lug 17 at one end by the spring 14, while the outer end of the finger is substantially interlocked vvltli the cap, which latter is provided with a pro jeotion 20, or other suitable means, engaging the adjacent end of the spring fin er 15 sothat this will not be accidentally dislodged from its position on the cap. The cap engaging end of the spring finger 15 is shown as perforated at 15' to engage the projecting part 20. a 1

t From the above it will be seen that the 75 end a hub 17 through which the pivot bolt formed recess or cavity device consists of a collar. which may readily attached to the radiator or other receptacle and may be permanently fastened thereto by a cement medium which can be introducm into the annular or otherwise 'When it is desired to fill the receptacle, it is only necessary to swing the cap 16 around on its pivot 11 and, therefore, uncover the opening of the collar 2. When the cap is in the closing position, it forms a substantially leak proof seat on the collar and prevents spillin The springfinger serves to hold the col ar closed or opened and also prevents it from rattling when in closed position, and, furthermore, holds it to its seat.

The frictional resistance to opening and closin of the cap member can he controlled by a justment of the pivot 11 passing through the spring washer it which, when released or compressed, varies'the resistance to returnin movement.

It is un erstood'lthat the collar portion 2 may be formed as an original and fixed part upon the receptacle as the radiator 18; or a tank, as may he desired and this will eliminate threading.

Various modifications and changes may he resorted to within the tion as claimed.

What is claimed is:

l. A. filling cap device for receptacles,

comprising a collar adapted to he secured to the filling nipple or mouth of the receptacleand having an overhanging flange, and a cap member movahly'connected to said collar and closeahle against and under said flange.

spirit of the inven incense 2. A filling cap device for rweptacles, comprising a collar adapted to be secured to the filling nipple or mouth of the receptacle, a cap member movably mounted upon said collar, and a resilient finger applicable to the top of and'for holding the cap memher in its several positions as to the collar.

3. A filling device for receptacles, comprising a collar applicable to the nipple of the receptacle and having an overhanging flange and a cap connected to the aforesaid collar and adapted to be swung laterally to an open or to a closm position and having a lateral stopping flange.

4. A filllng device for an automobile tank comprising a collar adapted to be attached to the filling nipple of the tank an annular pachng recessed into the upper face of the collar, a quick opening and quick. closing, laterally swinging closure member connected to the collar and adapted to seat upon said packing, and a laterally swinging resilient finger for pressing the cap member to its seat.

5. A. filling devioefor an, automobile tank comprisin a collar adapted to be attached to the fil lng nipple of the tank, a quick openi and quick closing, laterally swinging closure member connected to the collar and adapted to seat upon said packing, and resilient means for. pressing the cap memloer to its seat, said means including a bendable spring finger engaging and swinging with the movable cap member.

'ln testimony whereof l have signed my name to this specification.
